However, Mr Paxton has been on sick leave since December last year and has not made public the nature of his illness.

Mr Paxton said he wishes Suffolk next police chief every success in the future.

He said: “It has been the highlight of my career to return to Suffolk and serve alongside colleagues old and new as their Chief Constable.

“I have had the privilege of serving alongside some of the most dedicated and talented policing professionals in the best Constabulary in the country.

“As I move into retirement I want to wish the Police and Crime Commissioner and my deputy, Gareth Wilson, every success as they take on the challenge of resourcing and shaping the Constabulary to meet the challenges of the future.”

Tim Passmore, Police and Crime Commissioner said: “I would like to take this opportunity to thank Douglas for his contribution to policing in Suffolk and I wish him well in his retirement.
